"Oh no! The submarine has been hit! It looks like something is crashing down from above, and there are many of them!"

Chen Han shouted loudly. He saw objects constantly attacking the submarine from above the sonar detector, and he immediately maneuvered the submarine to evade them.

Lu Yuan looked up and saw, through the light, a large number of ice floes beginning to slide down into the water.

"That's not right, the ice cubes seem to be floating on the water, so why are they falling?"

Lu Yuan was somewhat surprised. He couldn't understand why these ice blocks were falling towards the bottom of the water, but he didn't have time to think about it. Then Chen Han shouted loudly, "Prepare for the impact!"

No sooner had he finished speaking than a violent impact was heard at the front of the submarine, causing the entire submarine to sway. Then, with a loud crack, it seemed that the stern of the submarine had also been hit. Chen Han glanced at the control equipment and his heart sank to the bottom.

"Oh no! The submarine's propeller has been damaged, and we can't control its direction!"

Lu Yuan immediately made a decision: "How far are we from the water now?"

"Fifty meters to go!"

"Alright, forget about the submarine. Dive up immediately, surface to the maximum height, and I'll take you away then!"

Without hesitation, Chen Han adjusted the submarine's surfacing speed to the maximum. The three of them felt as if the submarine was floating upwards rapidly, like a balloon in the water.

Suddenly, another violent impact came from above.

Then a large amount of ice floes pressed down on the submarine, preventing it from surfacing.

"There are ice floes blocking our way!"

A look of fear appeared on Chen Han's face. He looked up and suddenly felt water dripping down. He reached out and touched it.

"The protective layer on top of the submarine has been cracked; we must abandon ship and leave!"

As soon as he finished speaking, he felt a strong suction force, and the next second he appeared in a mysterious space. At this moment, Lu Yuan was holding the dimensional crystal necklace and then put on his protective suit.

Then Lu Yuan turned on the submarine's exit button and quickly crawled to the submarine's exit.

Before long, Lu Yuan appeared outside the submarine.
